An observational study in Hepatitis C and Pregnancy Complications, sponsored by Washington University School of Medicine. Recruiting at 2 sites in United States. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-06-09.
Sponsored by Washington University School of Medicine · Observational
Pregnant adults over the age of 18 who are seen in the Washington University obstetrics and gynecology, maternal fetal medicine or infectious diseases clinic or admitted to BJH with hepatitis C virus infection who have a history of past or current drug use
Participant Duration: Approximately 1 year.
Aims:
Aim 1 - Evaluate adherence and treatment completion rates when glecaprevir-pibrentasvir is started during pregnancy for women who use drugs.
Aim 2 - Evaluate patient experience with hepatitis C virus treatment during pregnancy.
Pregnant adults over the age of 18 with a history of either past or current drug use who are seen in the Washington University obstetrics and gynecology, maternal fetal medicine or infectious diseases clinic or admitted to BJH with hepatitis C virus infection who consent to participate in the study will be treated with glecaprevir-pibrentasvir.
All consented individuals will participate in four (4) in-person study visits. At the first in-person study visit, patients will receive information about hepatitis C virus treatment, complete testing for HIV and HBV and be assessed for cirrhosis. Patients who meet study criteria will initiate HCV treatment with glecaprevir-pibrentasvir. Patients will return for a second in-person study visit while on HCV treatment (between day 14-56) at which time they will complete a questionnaire about medication adherence and have HCV RNA testing performed. A third in-person study visit will occur at completion of HCV treatment at which time patients will again complete a questionnaire about medication adherence, and have HCV RNA testing performed. The final study visit will occur 4 weeks after completion of HCV treatment at which time patients will have HCV RNA testing performed. All labs that are included as part of the study are standard of care labs for all pregnant women, and are standard of care during HCV treatment (HCV RNA, CBC and CMP).
Additional information about the clinical course of infection (including HCV RNA testing obtained at the time of labor and delivery), and maternal and fetal outcomes will be abstracted from the medical record at 1 year post study enrollment.
All participants will be followed longitudinally in the medical record to ascertain maternal and fetal outcomes and HCV re-infections for up to 1 year post study enrollment.

Adults over the age of 18 with hepatitis C virus infection who are currently pregnant with a history of past or current drug use. Patients must have health insurance which covers hepatitis C virus treatment with direct acting antivirals and who agree to begin HCV treatment with glecaprevir-pibrentasvir during pregnancy. Participants pregnancies must have reached at least 10 weeks gestational age prior to initiation of medication.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
